Checking if redis works
|
1 2 3 |
# telnet redis 6379 set testkey 10 get testkey |
Example
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
root@ip-10-0-0-31:~# telnet news24redis.cylrbg.0001.use1.cache.amazonaws.com 6379 Trying 10.0.0.223... Connected to news24redis.cylrbg.0001.use1.cache.amazonaws.com. Escape character is '^]'. set testkey 10 +OK get testkey $2 10 quit +OK Connection closed by foreign host. root@ip-10-0-0-31:~# |
Count Number of Keys
To count number of keys, use
|
1 |
DBSIZE |
Example
|
1 2 3 4 5 6 |
root@ip-10-0-0-31:~# telnet news24redis.cylrbg.0001.use1.cache.amazonaws.com 6379 Trying 10.0.0.223... Connected to news24redis.cylrbg.0001.use1.cache.amazonaws.com. Escape character is '^]'. DBSIZE :4114 |
Here DBSIZE returned 4114, that means you have that much key/value stored in redis.
Flush ALl
To flush all keys, use
|
1 |
flushall |

In this server, we have PHP 7.0 installed. So we need to install packages for PHP 7.0
Here are the two packages for PHP 7.0
|
1 2 |
php70-php-pecl-redis.x86_64 : Extension for communicating with the Redis key-value store php70-php-phpiredis.x86_64 : Client extension for Redis |
Install it with yum
|
1 |
yum install -y php70-php-pecl-redis.x86_64 php70-php-phpiredis.x86_64 |
Now you need to restart web server, generally restarting apache will do. In this cause PHP is running as php-fpm under nginx, so we need to restart php-fpm with
|
1 |
systemctl restart php-fpm |
Installing Redis On CentOS 7
To install Redis on CentOS, run
yum install redis
Start redis with

Set redis to start on boot
|
1 |
systemctl enable redis |
Verify redis is running with
|
1 2 3 |
